I've been tasked in setting up an FTP server that will allow people on the outide of our network to log into a server & download documents. I know all the internals of setting up the external IP, bla bla bla....I'm just needing to get a better understanding on security & some experts opinions. Should I use Linux or Windows FTP server? What are some recomendations? I basically just want to be able to upload a document from my LAN to one of our internal FTP servers. Then in turn, let someone else on the outside know the external FTP IP address & a password so they can log into it & download it. I need it to be of the utmost secure environment...thanks for any input.
